JAR CLOSURE.

Application filed December T 0 all whom it may concern:

Be it known that I, GRIN C. Davis, a citizen of the United States, residing at Manistee, in the county of Manistee and State of Michigan, have invented a new and useful Jar Closure, of which the following is a specification.

Generally considered, this invention aims to provide a ar closure which will be sanitary, inexpensive to construct, neat in appearance, facile in operation and capable of affording an hermetic seal.

Specifically, the invention aims to improve the construction of the yoke whereby the cover is held on the body portion of the jar and to provide novel means "for mounting the yoke rotatably on the cover.

It is within the province 0-; the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, with in the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in side elevation, a device constructed in accordance with the invention; Figure 2 is a transverse section; and Figure 3 is a top plan.

In carrying out the invention, there is provided a receptacle or ar 1 having a neck 2 provided with a circumscribing shoulder 3, the neck upstanding above the shoulder to form a circumferential lip 1. The shoulder 3 carries oppositely disposed depending cams 5. In accordance with the common practice, the shoulder 3 supports a compressible gasket 6.

A cover 7 is provided, and has a depres sion 8. A boss 10 upstands from the cover 7 and is provided with an enlarged head 11, the depression 8 extending about the boss. The cover 7 is supplied with a depending circumferential flange 9 adapted to engage the gasket 6.

The receptacle 1 and the cover 7 may be made of any desired material, lass being the substance most commonly used.

The device includes a yoke 12, which ordi- Specification of Letters Patent.

n'arily, is made from relatively thin and lightsheet metal, the yoke comprising a body 1 1: having arms 15 at its ends, the arms 'bein disposed approximately at right angles to the body, and terminating in inwardly extended fingers 16 which may be inclined, as at 17, to correspond to the slope of the cams 5. In the body 14: of the yoke 12, an opening 18 is formed, the opening being of such a size as to receive the boss 10, but being slightly less in diameterthan the head 11 of the boss. The body 14 of the yoke 12 has oppositely disposed longitudinal slots, communicating with the opening 18. The constituent material of the yoke 12 is distorted to form a loop-shaped rib 20 extended about the opening 18 and the slots 19, the rib having extensions 21 prolonged upon the arms 15, and extending, if desired on the fingers 16, the parts 21 of the reinforcement running out to nothing, in some instances, on the fingers 16.

Owing to the "fact that the body 14 is provided with the slots 18, the material is weakened sufficiently so that the head 11 of the boss 10 may be passedthrough the opening 18, the material resuming its normal potion about the boss 10 beneath the head 11 as shown in Figure 2, the yoke 12 thus being mounted to swing on the boss 10. Owing to the fact that the loop-shaped rib 20 is provided, any weakening caused by the formation or the slots 19 is offset, the parts 21 serving to reinforce the arms 15 and the fingers 16. The yoke 12 is so constructed that it ma y be made out of sheet metal, the cost of production being reduced accordingly.

The operation of a device of the kind above mentioned is common and well known,

but. it may be stated briefly that when the yoke 12 is swung on the boss 10, the fingers 16 cooperate with the cams 5 and press the flange 9 tightly upon the gasket 6.

Having thus described the invention, what is claimed is 1. A jar closure comprising a cover having a boss provided with a head; and a yoke journaled and held on the boss beneath the head, the yoke having an opening receiving the boss and of less diameter than the head, the yoke being equipped with a slot communicating with the opening and providing for a distortion of the yoke suiiiciently to permit the head to pass through the opening.

A jar closure comprising a cover-having a boss provided with a head; and a yoke journaled' and held on the boss beneath the head, the yoke having angularly disposed arms provided With projecting fingers, the
